DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0036] The present invention is generally directed to collapsible and portable rocking chairs, and more particularly, a stowaway compact rocker especially suitable for outdoor use as a beach chair, lawn chair, and the like, where the rocker, in a set-up condition, can be rocked by a seated user, and where the rocker can be readily collapsed from the set-up condition to a compact collapsed condition for transportation and/or storage.
[0037] In the drawings and the description that follows, the present invention is illustrated and described with reference to stowaway compact rocker designs embodying the present invention. A first embodiment of such a rocker, generally designated as reference numeral 10, is illustrated in
[0038] Referring to
[0039] Referring to
[0040] The seating fabric 12, as mounted on the chair frame 14, is illustrated in
[0041] In preferred embodiments, the tube members 18, 20, 22 and 24 are internally shock-corded to facilitate ready and quick assembly and disassembly and allow for compact storage when the rocker 10 is not in use without risk of losing parts. This design also facilitates keeping the chair components together in a bundled condition when the rocker 10 is collapsed, as shown in
[0042] Referring to
[0043] Various elongated structural parts or members comprising the chair frame 14 are preferably constructed from tubular material of circular cross-section, or in the alternative, or non-circular cross-section, such as, for example, extruded aluminum tubing having oval, elliptical, or square cross-section. Additionally, elongated structural parts and members illustrated and described herein, though illustrated as single piece in accordance with preferred embodiments of the present invention, may be constructed from multiple pieces collectively functioning in an equivalent manner to a single-piece construction without departing from the spirit and principles of the present invention. Accordingly, use of the terms tube, member or tube member herein are intended to cover single-piece and multi-piece constructions, unless otherwise specified herein.
[0044] Referring to
[0045] Though multiple plate springs are illustrated in the embodiment of
[0046] Referring back to
[0047] The movable portion of the central hub 16 comprises a transversely-extending upper support member 26, and left and right seat tube mounts 36L and 36R, each having mirrored construction to one another, that are mounted for movement with the upper support member 26. The seat tube mounts 36L, 36R are preferably positioned adjacent to, but offset from, respective leg mounts 30L, 30R, as illustrated in
[0048] As noted, in preferred embodiments, the central hub 16 further includes a rocking mechanism comprising compliant linear-flex or cantilevered plate members, hereinafter referred to as spring plates disposed within the central hub 16. As shown in the embodiment of
[0049] In preferred embodiments, the spring plates 42 are transversely spread out between the left and right sides of the chair frame 14. Alternatively, the springs plates 42 can be more centrally located, or even replaced by a single spring plate, such as illustrated in
[0050] The spring plates 42 are secured at each end to the upper and lower transverse support members 26 and 28, preferably by bolts or pins 44. As noted, the spring plates 42 can comprise multiple distinct plates, positioned tightly together in the transverse center of the chair frame 14 or spread out along the transverse extent of the central hub 16. In the alternative, a single centrally-positioned spring plate 42 may be used without departing from the principles and spirit of the present invention. Additionally, though the upper and lower transverse support members 26 and 28 are illustrated as single-piece members, the transverse support members 26 and 28 can be constructed from multiple pieces designed to collectively bridge and connect the left and right side of the chair frame 14 to respectively define the stationary portion and movable portion of the chair frame 14 and also support the respective ends of the spring plate(s) 42.
[0051] Referring to
[0052] Moreover, a gap is provided between sets of seat tube mounts 36L, 36R and leg mounts 30L, 30R. This gap allows for pivoting motion of the moveable portion of the chair frame 14 relative to the stationary portion without the portions contacting and interfering with the rocking movement of the chair 10. Additionally, when a user is seated in the chair 10, and especially when said user has greater weight, the movable portion of the chair frame 14 may sag more closely to the stationary portion. The predefined gap permits a certain amount of sagging without inhibiting intended operation of the rocker 10. The gap is further defined by the shape of the spring plates 42as illustrated in
[0053] The afore-mentioned horizontal plane for the spring plates 42 in their state of rest is defined in relation to the ground surface on which the chair 10 is set-up. Notably, if the chair 10 is set-up on a slight incline or decline, then the horizontal plane will not be a true horizontal plane, but rather generally parallel to a virtual plane defined by the support surface (i.e., ground). In further reality, the spring plates 42 can have some nominal deviation from the true horizontal plane (or the plane parallel to the virtual plane of support surface) in accordance with the principles and spirit of the present invention. Indeed, as illustrated in the embodiments of
[0054] In use of the set-up stowaway compact rocker 10 for rocking motion, when the seated user leans back on the back-rest or forward on the seat, the movable portion of the central hub 16 will pivot or rotate backwards and forward relative to the stationary portion of the central hub 16. Thus, the upper support member 26 and the seat tube mounts 36L and 36R attached thereto will rotate about a central transverse axis relative to the stationary portion of the chair frame 14namely, the lower support member 28, the leg tube mounts 30L, 30R and the front and rear legs 18 and 20. The rocking force applied by the seated user generates a spring force in the spring plates 42. In use, the front and rear legs 18 and 20 remain stationary, as the set-up chair 10 is intended to be positioned on a ground surface. The stationary front and rear legs 18 and 20 stabilize the lower support member 28 through the leg tube mounts 30L, 30R. Thus, the movable portion of the chair frame 14namely, the upper support member 26, the seat tube mounts 36L, 36R, and the seat tubes 22 and back-rest tubes 24, will be permitted to pivot with flexing of the spring plate 42. As a result, the seat and back-rest portions of the rocker 10 will also move in backwards and forwards directions. The rocking motion of the movable portion of the central hub 16 will cause the spring plates 42 to bend and flex with motion of the movable portion of the rocker 10. The flexing of the spring plates 42 essentially creates a spring or compliant member supplying the rocking action of the rocker seat, flexing in one direction and then the other in connection with back-and-forth rocking motion of the rocker 10.
[0055] To collapse the stowaway compact rocker 10, the seating fabric 12 is removed from the chair frame 14. Then, the frame tube members 18, 20, 22 and 24 described herein are disengaged from the central hub 16 to create a seat bundle (
[0056] As illustrated in
[0057] In accordance with preferred embodiments of the present invention, each frame membernamely, the front leg tubes 18, the rear leg tubes 20, the seat tubes 22 and the back-rest tubes 24may include means for connecting and securing the frame members in the collapsed and bundled condition of the rocker 10, such as illustrated in co-pending U.S. application Ser. No. 17/648,088, incorporated herein by reference.
[0058] An alternate embodiment of the present invention is illustrated in
[0059] Similar to the embodiment of
[0060] Another alternate embodiment of the present invention is illustrated in
[0061] Another alternate embodiment of the present invention is illustrated in
[0062] As illustrated, the rocker mechanism comprises linear-flex springs in the form of multiple vertically disposed spring plates 342 spread along the transverse dimension of the chair frame 314. Though multiple plates 342 are shown, as noted above, the design can utilize a singular, centrally-located spring plate without departing from the principles and spirit of the present invention. As further shown, the spring plates 342 can be reinforced to increase rigidity or stability. Still further, the rigidity and flexibility of these spring plates 342 may be adjustable to accommodate users of different weights, or to simply modify the rigidity and flexibility of the compliant members and the rocking capability and motion. An alternate arrangement for the vertically-disposed spring plates 342 is illustrated in
[0063] As with other embodiments shown and described herein, the spring plates 342 are connected between a lower transverse support member 328 belonging to a stationary portion of the chair frame 314 and an upper transverse support member 326 belonging to a movable portion of the chair frame 314. Referring to
[0064] As previously noted, the compliant spring plate used to impart rocking capability between the movable portion and the stationary portion of the chair frame of the present invention may be horizontally disposed, as illustrated in the embodiments of
[0065] When the rocker 310 is not needed, the rocker 310 can be collapsed into a collapsed condition, as illustrated in
[0066] In embodiments of the present invention, the rocking capability for the stowaway compact rocker could be adjustable to change the rigidity and flexibility of the rocking mechanism to accommodate different user weights and/or varied preferences of seated users. Additionally, embodiments may provide an adjustable rocking mechanism so that the rocking capability and comfort level can be optimized to the user's desires, said rocking mechanism comprising compliant members, such as plate springs, linear-flex springs, cantilever springs, leaf springs, torsion springs or the like.
[0067] Alternative compliant members may also be used to impart the rocking motion between the movable and stationary portions of the central hub. For example, leaf springs or flexible tension springs of various design can be used in a similar manner to the plate or linear flex springs shown and described herein.
[0068] The images and description of embodiments herein generally illustrate a stowaway compact rocker with front-to-back rocking motion. Notably, the present invention also has utility providing side-to-side rocking motion, such as for a pack seat concept or a baby cradle or bassinet, without departing from the principles and spirit of the present invention. Such alternate designs would utilize the general concepts described herein, namely a central hub design having a stationary portion and a movable portion, wherein said central hub would extending front-to-back instead of transversely, and more preferably utilize the plate and linear flex springs relatively positioned between upper and lower support members extending front-to-back so that the seat or cradle portion will rock side-to-side.
[0069] In an alternate embodiment of the stowaway compact rocker in accordance with the present invention, a storage/carrying bag can be provided to hold the collapsed and bundled rocker, such as illustrated in
[0070] Still further, use of the bag over the top of the back-rest can provide stability to the set-up rocker. As noted, a headrest brace can be used, but is not necessary. Instead, the carrying bag can act as the headrest brace, and in this regard, can include a reinforcing member (such as a sewn-in brace member) to improve stability of the set-up chair.
[0071] Additionally, the storage/carrying bag can include additional storage pockets for holding personal effects when using the set-up chair with the bag placed over the top of the back-rest.
[0072] The foregoing description of embodiments of the present invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the form disclosed. Obvious modifications and variations are possible in light of the above disclosure. The embodiments described were chosen to best illustrate the principles of the invention and practical applications thereof to enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as suited to the particular uses contemplated.
